Possible virus on C. intermedia?

[papayj]

I found several disturbing signs on my Catt. intermedia var. orlata 'Rio'. There are several dark purplish spots on the leaves and some of them even show light yellowish, chlorotic streaks. I fear this might be virus. And virus test kits are not widely available in my country. (Unless you are in big horticultural business) I guess I have to throw this poor guy away...
